Referring to the drawing, 7 indicates the driving shaft which may be the main shaft of the engine or a secondary shaft driven through suitable gearingtherefrom. Mounted on the shaft, and rotating with it, is a frame comprisin a lower head 8 that is keyed or otherwlse secured to the driving shaft and an upper head 9. These heads are connected by two upright columns or members 10. On the lower head are mountshown in Fig. 6. As both weights'are similar,' a descrlption of one of them will be suflicient. Y

inthe present instancean inner ring 15 tted snugly on the pivot and an outer ring. 16 fitted snugly into a boss 17 formed on the lower head. The balls 18 are confined in place between the rlngs. The axes of the pivots are located in the same horizontal plane and are parallel to each other and are equidistant from the axis of the governor as a whole. To insure satisfactory operation lost motion between the parts is eliminated as far as possible. Each of the rollers 13 is supported by a ball bearing 19 of a construction similar to that 7 described but smaller in diameter. The pivots for these rollers extend bearing comprisin thronghthe arm 12 and are prevented from moving endwise by cotter pins or other means. The weights are beve ed slightly at their outer ends as indicated at 20, said Ject'mns 21 on the column 10, as shown m.

'Fig. '2, and limit the inward movements of the weights. The weights are also provided with oil chambers and oil feeding grooves as will appear later. rame partly in section and taken at right The upper end of the shaft 7 is provided with a. socket and located therein and making a sliding fit is a spindle 21. Mounted on the spindle and engaging a shoulder'thereon The rollers 13 The upper surface of and mounted thereon is l washer 23 which forms the lower-seat for the s rin 24 that'opposes the outward movemen s o the weights. The object in rounding the upper surface of the abutment and the under surface of the washer is to insure a uniform pressure ofthe springon tendency of y le to one side Theup r head 9 of the frame is proa central screw threaded orifice,

eral notches to receive the thin plate 27 t at acts as a lock to prevent the nut from turning after it has once been adjusted. By changing the position of the nut the tension on the spring can be changed and hence the speed of the engine. When it is desired to adjust the governor for widel diflerent speed conditions, a spring of di erent character may be readily substituted without changing the other parts. The nut is also provided with an oil chamber and grooves, as will appear later.

On the upper end of the spindle is mounta thrust collar by means of which the axial movements of the spindle are transmitted to the governor lever 26. The end of the spindle is reduced in section to form a shoulder and mounted thereon is a hardened steel disk 27, The disk is held in place by a tubular spacer 28, which, in'turn, is held'by a nut on the end of the spindle. Above and below the disk are ball bearings 29 of suitable construction. Above and below the ball bearings are hardened steel thrust plates 30 which are fitted snugly into the casing 31 and separated by the proper distance by the tubular spacer 32. The casing 31 is provided with two pins 33, one benig shown in dotted lines, arranged one on each side, transmit axial movements of the spindle to it. The spindle 21, disk 27, and ball bearings 29 are somewhat smaller in diameter than the bored openings in the casing 31, to

' permit the latter to move slightly with respect to the spindle as the lever 26 moves on its fulcrum. The upper end of the cas ing is provided with a nut 33 which, when screwed into place, clamps .the hardened thrust plates 30 in position. It is also provided with an oil reservoir and cover 34 therefor.

The governor is inclosed by a casin 35 which is fixed on some suitable part of the engine frame that carries the bearing 36 of the shaft 7. Mounted on top of thecasing is a cover or cap 36 having a central orifice to receive and guide the spindle 21. The top surface of the cap is beveled toward said orifice so that .oil will flow toward the. spindle as will appear later. Mountedon top of the casing is a bracket 37 which carries the fulcrum 38 for the governor lever. This lever is provided with an upwardly extending arm 39, and mounted thereon is a spring pressed head 40 which has a pin 41 t at enters a hole in the bellcrank lever 42, the latter bein sleeved on the fulcrum 38 and provided with a handle 43. The arm also carries an adjusting screw 44 that forms a back-stop'for the lever 42. The other end of the lever 42 is connected to a tubular rod 45 which is arranged-to control the action of one or more valves of the pump which supplies fuel to the internal combustion engine. As an example, the

which engage the lever 26 and one another disposed pieces 0 rod 45 may control the suction valves of the fuel pump. Under some conditions notably in starting the engine, it is sometimes desirable to supply the pulverizer of the engine with a different-usually, ,a greater amount of oil than for normal operation. The arrangement of the bell-crank lever 42 and the arm 39 permit of this. The operator by manipulating the handle 43 can con- .trol the fuel pump or pumps to the exclusion of the speed overnor, thereby varying the supply of fee at will. Just as soon as the operator releases the handle, it returns to the position shown and the governor resumes its normal flmction.

Acting on the right hand end of the governor lever is a means whereby the governor can be loaded or unloaded to change the -speed while the engine is running. It

comprises a head 45*, having a knife edge on its under side that rests on the'lever 26". Above the head is a coiled compression spring 46 whose tension can a nut threaded on the rod 47.

It is of the lubricate the parts in order that the governor may regulate the speed of the engine within narrow limits at all times. This is out of the question if the parts moving on get dry and wear. Even a 'very slight lost-motion in one member due to wear or imperfect workmanship will seriously affect the regulation. To this end a small amount of lubricating oil is poured 'into the chamber 48 as required. Generally it will be found best to put a wick in this so that the oil will be moved by capillary attraction. From this point the oil flows through the vertical holes 49 on to the thrust plate 30 and through its central opening to the ball bearings. After lubricating the greatest importance to fully be adjusted by v chamber and stick its ends into the holes 49, I

thrust bearing the oil collects in the bottom of clearance and down the shaft to the slightly coned to of'thecap 36. Opening into the bore of t e cap are as many Oll carryin passages 50 as are necessary. We have ound three to be satisfactory. Other holes 51 are also provided to take care of any excess oil. The oil passing through the holes 50 in the stationa cap falls into the chamber 52 in the rotating nut 25. From the chamber it is thrown by downwardly extending passages into the annular chamber 53 in the head 9, Fi 1. It" lower end 0 the nut is to be noted that the projects below the upper surface of the ead, and that the parts are so shaped that oil will be discharged into the chamber rather than outside. The oil flows from the annular chamber 53 down posed passages 54 in the columns 10, Fig. 4. At the ends of the assages are horizontally tubmg 55 that form the casing-31 andflows through the shaft centrifugal force through the the vertically dishers 56-in-thewe1ghts.
